//	加密的模式
//	ECB：是一种基础的加密方式，密文被分割成分组长度相等的块（不足补齐），然后单独一个个加密，一个个输出组成密文。
//	CBC：是一种循环模式，前一个分组的密文和当前分组的明文异或操作后再加密，这样做的目的是增强破解难度。
//	CFB/OFB实际上是一种反馈模式，目的也是增强破解的难度。
//	ECB和CBC的加密结果是不一样的，两者的模式不同，而且CBC会在第一个密码块运算时加入一个初始化向量。
//	字节填充方式（Byte padding）
//	ANSI X.923：... | DD DD DD DD DD DD DD DD | DD DD DD DD （00 00 00 04）|【除了最后字节，其他填0】
//	ISO 10126：.... | DD DD DD DD DD DD DD DD | DD DD DD DD （81 A6 23 04）|【除了最后字节，其他随机】
